Nuxt Compiler Constants Utility

nuxt-define is a utility package designed for Nuxt module authors to uniformly define compiler constants across all supported Nuxt builders, including Vite, Webpack, and Rspack. It abstracts away the builder-specific mechanisms for constant definition, providing a single `addDefinePlugin` function. This allows module developers to avoid adding builder-specific dev dependencies, reducing dependency noise and ensuring consistent behavior regardless of the underlying bundler chosen by the Nuxt project. The current stable version is 1.0.0, suggesting a mature initial release. As a utility, its release cadence is likely tied to Nuxt ecosystem updates or bug fixes, rather than a strict schedule. Its key differentiator is simplifying cross-builder constant definition and enabling effective dead code elimination for feature flags during the build process, leading to optimized bundles.
